Employing the innovative NeoTec rapid opening and closing mechanism, the Manfrotto 458B Neotec Pro Photo Aluminum Tripod has legs that open up by simply pulling down on each one, and automatically lock into any position, with no screws, knobs or levers to tighten. By pressing the release button at the top of the legs the legs can be collapsed again fully, or locked at any intermediate point for perfect positioning. This mechanism exerts more locking power the heavier the weight pushing down on it from above. Other professional features include an improved minimum-maximum height range and a 90° horizontal center column feature.
